Chris Weitz hopes the loving couple ‘retain their essential humanity’ — are you worried about them too?

Robert Pattinson and Kristen Stewart have kept down-to-earth in the midst of Twilight hysteria, but one of the series’ directors worries they might get big heads because of fame!

New Moon director Chris Weitz says he loves Rob, 25, and Kristen, 21, but he fears their sudden, massive success could change them as people, the Philippine Daily Inquirerreports.

“I want to see them succeed,” Chris said. “I want to see them retain their essential humanity. I like them very much. What I also wish for them are happy lives that aren’t impinged on too much by the downside of the great things that have happened to them.”

What do you think, HollywoodLifers — will fame and money change Rob & K-Stew?
